Description

本発明は、電動歯ブラシ、特に複数の動作で作動するキャリアを有する電動歯ブラシに関する。   The present invention relates to an electric toothbrush, and more particularly to an electric toothbrush having a carrier that operates in a plurality of operations.

可動キャリアを利用した電動歯ブラシは、当該技術分野において既知である。   Electric toothbrushes using movable carriers are known in the art.

ところが、複数の動作を有するキャリアを利用した電動歯ブラシの提供に継続する要望があり、それは、機械的に効率がよく、及び／又はより小型でよりコンパクトな装置である。   However, there is a continuing need to provide an electric toothbrush that utilizes a carrier with multiple motions, which is a mechanically efficient and / or smaller and more compact device.

電動歯ブラシが提供される。電動歯ブラシは、ハンドル、キャリア及び長手方向軸線を有するヘッド、並びにハンドルとヘッドの間に配置されるネックを有してよい。モーターは、ハンドル内に配置されてよい。シャフトは、モーターに動作可能に接続されてよい。シャフトは、キャリアに動作可能に接続されてよく、第１動作でキャリアを駆動する。キャリアは、使用者の力を受けた時、第２動作で駆動してよい。   An electric toothbrush is provided. The electric toothbrush may have a handle, a carrier and a head having a longitudinal axis, and a neck disposed between the handle and the head. The motor may be disposed in the handle. The shaft may be operably connected to the motor. The shaft may be operably connected to the carrier and drives the carrier in a first motion. The carrier may be driven in a second motion when receiving the user's power.

ここで本発明の各種実施形態を参照し、その実施例を添付図面で説明するが、類似した番号は図全体にわたって同じ要素を表す。図１に関して、電動歯ブラシ２０がここで説明される。電動歯ブラシ２０は、ハンドル２２、ネック２４及びヘッド２６を備えてよい。ネック２４は、ハンドル２２と一体的に形成されるか、又は別個の構成要素として供給されてもよい。ハンドル２２は、ハンドル２２の一部を螺合で係合するキャップ２８を有してよい。電動モータ３０は、電圧源と共にハンドル２２内に配置されてよい。電圧源は、ハンドル２２内に配置されるクレードル３４に収納される１以上のバッテリ３２の形態で設けられてよい。モーター３０は、回転式出力軸及び回転式出力軸に取り付けられた出力歯車３８を有してよい。出力歯車３８は、被動歯車４０を係合し、更には被動歯車４０の偏心柱（eccentric post）３７を係合する細長いスロット４５を備える連結具４４を有するシャフト４２に動作可能に接続されてよい。スロット４５は、シャフト４２の長手方向軸線４７に沿ってそろえられてよい。シャフトは、ハンドル２２又はネック２４により捕捉され得るブッシング４６を含んでよい。ブッシング４６は、ブッシング４６の周りにシャフト４２を旋回可能ないかなる可撓性材料で形成されもよい。好適な材料には、天然又は合成ゴムなどのエラストマーポリマーを挙げることができる。ブッシング４６は、旋回軸のように機能し、その周りをシャフト４２が回転する。ブッシング４６の位置は、ヘッド２６に隣接するシャフト４２の末端部で所望の大きさの側方向動作を実現するため、シャフト４２の全長に沿って変更されてよい。被動歯車４０が回転すると、シャフト４２は、ブッシング４６の周りを側方向動作で旋回できる（図２参照）。シャフト４２の側方向動作は、実質的に又は完全に１つの平面で起こってよい。   Reference will now be made to various embodiments of the invention, examples of which are illustrated in the accompanying drawings, wherein like numerals represent the same elements throughout. With reference to FIG. 1, an electric toothbrush 20 will now be described. The electric toothbrush 20 may include a handle 22, a neck 24 and a head 26. The neck 24 may be formed integrally with the handle 22 or supplied as a separate component. The handle 22 may have a cap 28 that engages a part of the handle 22 by screwing. The electric motor 30 may be disposed in the handle 22 along with a voltage source. The voltage source may be provided in the form of one or more batteries 32 housed in a cradle 34 disposed within the handle 22. The motor 30 may have a rotary output shaft and an output gear 38 attached to the rotary output shaft. The output gear 38 may be operatively connected to a shaft 42 having a connector 44 with an elongated slot 45 that engages the driven gear 40 and also engages an eccentric post 37 of the driven gear 40. . The slots 45 may be aligned along the longitudinal axis 47 of the shaft 42. The shaft may include a bushing 46 that may be captured by the handle 22 or the neck 24. The bushing 46 may be formed of any flexible material that can pivot the shaft 42 about the bushing 46. Suitable materials can include elastomeric polymers such as natural or synthetic rubber. The bushing 46 functions like a pivot axis, and the shaft 42 rotates around the bushing 46. The position of the bushing 46 may be varied along the entire length of the shaft 42 to achieve a desired amount of lateral movement at the distal end of the shaft 42 adjacent the head 26. As the driven gear 40 rotates, the shaft 42 can pivot around the bushing 46 in a lateral direction (see FIG. 2). The lateral movement of the shaft 42 may occur substantially or completely in one plane.

更に、図１に示されるように、ヘッド２６は、上部ハウジング７０（図８参照）、中央部ハウジング７２及び下部ハウジング７４から作製されてよい。ヘッド２６は、第１の自由端４８、及びネック２４を係合する第２の自由端５０を有してよい。ヘッドは、１以上のキャリアを含んでよい。電動歯ブラシ２０は、１つ又は複数のキャリアを備えてよい。第１キャリア５２は、第１末端部４８に隣接して配置されてよく、第２キャリア５４は、第２末端部５０に隣接して配置されてよい。図３に示すように、第１キャリアは、ヘッド２６の長手方向軸線５８に実質的に垂直である軸線５６の周りを振動してよい。図４に示されるように、第２キャリア５４（５２）は、ヘッド２６の長手方向軸線５８に垂直な側方向に又は側方向動作で往復運動してよい。図４に示される側方向動作が、ヘッド２６の長手方向軸線５８に実質的に垂直である限りは、第２キャリア５４（５２）の他の側方向動作が付与され得ると予想される。例えば、第２キャリア５４（５２）は、ピン又はヒンジ５３の周りを揺動又は旋回してもよい。図５に示されるように、ピン又はヒンジ５３は、異なる種類の側方向動作を付与するため末端部又は中央部等の第２キャリア５４（５２）の他の位置に備えられてよい。   Further, as shown in FIG. 1, the head 26 may be made from an upper housing 70 (see FIG. 8), a central housing 72 and a lower housing 74. The head 26 may have a first free end 48 and a second free end 50 that engages the neck 24. The head may include one or more carriers. The electric toothbrush 20 may include one or more carriers. The first carrier 52 may be disposed adjacent to the first end portion 48, and the second carrier 54 may be disposed adjacent to the second end portion 50. As shown in FIG. 3, the first carrier may oscillate about an axis 56 that is substantially perpendicular to the longitudinal axis 58 of the head 26. As shown in FIG. 4, the second carrier 54 (52) may reciprocate in a lateral direction or in a lateral motion perpendicular to the longitudinal axis 58 of the head 26. As long as the lateral motion shown in FIG. 4 is substantially perpendicular to the longitudinal axis 58 of the head 26, it is anticipated that other lateral motion of the second carrier 54 (52) may be imparted. For example, the second carrier 54 (52) may swing or pivot about a pin or hinge 53. As shown in FIG. 5, pins or hinges 53 may be provided at other locations on the second carrier 54 (52), such as the end or center, to provide different types of lateral motion.

図６及び７に示されるように、シャフト４２の末端部６６は、動作可能に第１キャリア５２（５４）のスロット６８を係合し、軸線５６周りの振動で第１キャリア５２（５４）を作動してよい。図８に示されるように、シャフト４２は、第２キャリア５４（５２）のカムフォロア６０を通過してよい。カムフォロア６０は、シャフト４２の部分を収容してよい。通常、スロット６４が、側方向動作で第２キャリア５４を誘導するよう、カムフォロア６０は、ヘッド２６のスロット６４内に収容されてよい。   As shown in FIGS. 6 and 7, the distal end 66 of the shaft 42 operably engages the slot 68 of the first carrier 52 (54) and vibrates the first carrier 52 (54) around the axis 56. May work. As shown in FIG. 8, the shaft 42 may pass through the cam follower 60 of the second carrier 54 (52). The cam follower 60 may accommodate a portion of the shaft 42. Typically, the cam follower 60 may be housed within the slot 64 of the head 26 so that the slot 64 guides the second carrier 54 in a lateral motion.

スロット６４の部分は、可撓性壁７６により側面に位置されてよい。可撓性壁７６は、ヘッド２６の長手方向軸線５８に対して横方向に向けられてよい。可撓性壁７６は、第２キャリア５４が使用者の力を受ける時、ヘッド２６の長手方向軸線５８に沿った動作で第２キャリア５４の運動に備えてよい。すなわち、使用者が電動歯ブラシ２０をオンにする時、第２キャリア５４は、側方向に作動するだけでよい。だが、使用者が歯をブラシングする時、使用者は、側方向動作を越える方向と動作で第２キャリア５４を操作する力をおそらく投入する。これらの力には、一般にヘッド２６の長手方向軸線５８に沿って第２キャリア５４を作動する力がおそらく含まれる。可撓性壁７６は、ヘッド２６の長手方向軸線５８に沿って第２キャリア５４を多少移動できるであろう（図９参照）。使用者により操作される時の第２キャリア５４の動作は、楕円形７８、円等の動作であってよく、したがって標準的なブラシング動作と矛盾しない。第２キャリア５４が第１動作に限られている時（例えば、ヘッドの長手方向軸線に対して側方向）、ブラシの電池電力は、通常保存される、というのは歯をブラッシング又はフロスする時、使用者の操作又はバイアスさせる力は、第１動作に対して作用するかわりに第２動作に移動されるからである（例えば、ヘッドの長手方向軸線に沿って又はヘッドの長手方向軸線と一直線となって）。ただ単に力を入れるだけで、かつて第１動作に対して作用した使用者の力が、今度は第２、第３、第４等の動作に使用される。   The portion of the slot 64 may be located on the side by the flexible wall 76. The flexible wall 76 may be oriented transverse to the longitudinal axis 58 of the head 26. The flexible wall 76 may provide for movement of the second carrier 54 in motion along the longitudinal axis 58 of the head 26 when the second carrier 54 is subjected to a user force. That is, when the user turns on the electric toothbrush 20, the second carrier 54 only needs to be operated in the lateral direction. However, when the user brushes the teeth, the user will likely apply a force to manipulate the second carrier 54 in a direction and motion beyond the lateral motion. These forces probably include forces that actuate the second carrier 54 generally along the longitudinal axis 58 of the head 26. The flexible wall 76 will allow some movement of the second carrier 54 along the longitudinal axis 58 of the head 26 (see FIG. 9). The operation of the second carrier 54 when operated by the user may be an ellipse 78, circle, etc., and is therefore consistent with standard brushing operations. When the second carrier 54 is limited to the first movement (eg, lateral to the longitudinal axis of the head), the battery power of the brush is normally stored, when brushing or flossing teeth This is because the user's operating or biasing force is moved to the second motion instead of acting on the first motion (e.g., along the longitudinal axis of the head or in line with the longitudinal axis of the head). Become). Simply applying force, the user's force that once acted on the first action is now used for the second, third, fourth, etc. actions.

可撓性壁７６は、使用者の力が可撓性壁７６に対して第２キャリア５４を作動するまで第２キャリア５４をバイアスできない。これは、第２キャリアが可撓性壁の間を自由に動きまわる空間が無くなるように可撓性壁７６をすぐ隣接した第２キャリア５４に向けることにより達成できる。又、第２キャリア５４と可撓性壁７６の間に所望の大きさの空間を残してもよい。更に、１つの可撓性壁７６を使用し、使用者の力を受けた時に移動するための限定された経路を第２キャリア５４に備えることがおそらく望ましいであろう。   The flexible wall 76 cannot bias the second carrier 54 until a user force actuates the second carrier 54 against the flexible wall 76. This can be accomplished by directing the flexible wall 76 to the adjacent second carrier 54 so that there is no space for the second carrier to move freely between the flexible walls. Further, a space having a desired size may be left between the second carrier 54 and the flexible wall 76. In addition, it would probably be desirable to use a single flexible wall 76 and provide the second carrier 54 with a limited path for movement when subjected to user force.

又、カムフォロア６０が可撓性壁７６で完全に取り囲まれ、その結果、更に、第２キャリア５４の第１動作が使用者の力によって補完され、その結果、第２キャリア５４の側方向動作が使用者の力で拡大され得ることが予想される。   Also, the cam follower 60 is completely surrounded by the flexible wall 76, so that the first movement of the second carrier 54 is further supplemented by the user's force, so that the side movement of the second carrier 54 is It is expected that it can be expanded with the power of the user.

ヘッド２６のハウジング（例えば、７０，７２、及び７４）の構造の一部を可撓性にする代りに、少なくともカムフォロア６０の部分を可撓性にすることにより同じ動的動作が実現されてよい。カムフォロア６０は、天然又は合成ゴム等のエラストマーポリマーを包含する好適な材料を含んでよい。   Instead of making a part of the structure of the housing of the head 26 (eg, 70, 72, and 74) flexible, the same dynamic motion may be achieved by making at least a part of the cam follower 60 flexible. . Cam follower 60 may comprise any suitable material including elastomeric polymers such as natural or synthetic rubber.

図１０に示されるように、電動歯ブラシ２０は、ヘッド２６の長手方向軸線５８に沿って往復運動する１つのキャリア８０だけを備えてよい。ヘッド２６は、その長手方向軸線５８に沿って動く細長いスロット６４を有する主ハウジング８２を備えてよい。スロット６４は、ネック２４収容末端部８８のタブ８６を収容する溝８４を有してよい。又、主ハウジング８２は、ネック２４開口部９２に収容されるボールジョイント９０を有してよい。キャリア８０は、バネクリップ９４に固着又は動作可能に接続されるアーム９０を有してよい。   As shown in FIG. 10, the electric toothbrush 20 may include only one carrier 80 that reciprocates along the longitudinal axis 58 of the head 26. The head 26 may include a main housing 82 having an elongated slot 64 that moves along its longitudinal axis 58. The slot 64 may have a groove 84 that receives the tab 86 of the neck 24 receiving end 88. The main housing 82 may also have a ball joint 90 that is received in the neck 24 opening 92. The carrier 80 may have an arm 90 that is fixedly or operably connected to the spring clip 94.

キャリア８０は、シャフト４２’により細長いスロット６４に沿って往復運動し、このようにしてヘッド２６の長手方向軸線５８に沿って又は長手方向軸線５８と一直線となって往復運動してよい。キャリア８０が、細長いスロット６４に沿った動作で作動すると、バネクリップ９４が、ネック２４の左側壁９６と右側壁９８に沿ってまたがり、その結果、バネクリップ９４の左足１００と右足１０２が、左側壁９６と右側壁９８に対してバイアスされてよい。あるいは、バネクリップ９４（６４）は、左右側壁９６及び９８の間を自由に動きまわってもよい。   The carrier 80 may reciprocate along the elongated slot 64 by the shaft 42 ′ and thus reciprocate along or in alignment with the longitudinal axis 58 of the head 26. When the carrier 80 is actuated in motion along the elongated slot 64, the spring clip 94 straddles along the left side wall 96 and the right side wall 98 of the neck 24 so that the left foot 100 and the right foot 102 of the spring clip 94 are on the left side. It may be biased against wall 96 and right side wall 98. Alternatively, the spring clip 94 (64) may move freely between the left and right side walls 96 and 98.

バネクリップ９４（６４）は、キャリア８０が使用者の力を受ける時、ヘッド２６の長手方向軸線５８を横切る動作でキャリアの運動に備えてよい。すなわち、使用者が電動歯ブラシ２０をオンにする時、キャリア８０は、ヘッド２６の長手方向軸線５８に沿って作動するだけでよい。だが、使用者が歯をブラシングする時、使用者は、一般にヘッド２６の長手方向軸線５８を横切るキャリア８０の動作をおそらく操作し、従って、バネクリップ９４（６４）は、キャリア８０をヘッド２６の長手方向軸線５８を横切って多少移動できる。従って、キャリア８０が、ヘッド２６の長手方向軸線５８に沿って作動しているとき、それは、ヘッド２６の長手方向軸線５８を横切り作動されてもよい。キャリア８０が使用者の力を受けている時、それは、アーム９０の周りを旋回させてもよい。従って、図１１及び１２に示されるように、キャリア８０の前側部分１０４がヘッド２６の長手方向軸線５８を横切って１つの方向に作動されているとき、キャリア８０の後側部分１０６はヘッド２６の長手方向軸線５８を横切って反対方向に作動される。キャリア８０は、キャリア８０の長手方向軸線１１６が主ハウジング８２（１）の長手方向軸線１１４から約５〜約５０度、約１５〜約３０度、又は約２０〜約２５度であるように旋回されてよく、これに対してキャリア８０が旋回されない時、その長手方向軸線１１６は、一般に主ハウジング８２の長手方向軸線１１４と一直線となっており、従って、一般にシャフト４２’の長手方向軸線４７と一直線となる。   The spring clip 94 (64) may provide for movement of the carrier in a motion across the longitudinal axis 58 of the head 26 when the carrier 80 is subjected to a user force. That is, when the user turns on the electric toothbrush 20, the carrier 80 need only operate along the longitudinal axis 58 of the head 26. However, when the user brushes the teeth, the user will probably manipulate the movement of the carrier 80 generally across the longitudinal axis 58 of the head 26, and thus the spring clip 94 (64) causes the carrier 80 to move the carrier 80 to the head 26. Some movement is possible across the longitudinal axis 58. Thus, when the carrier 80 is actuated along the longitudinal axis 58 of the head 26, it may be actuated across the longitudinal axis 58 of the head 26. When the carrier 80 is receiving user force, it may pivot about the arm 90. Thus, as shown in FIGS. 11 and 12, when the front portion 104 of the carrier 80 is actuated in one direction across the longitudinal axis 58 of the head 26, the rear portion 106 of the carrier 80 is Actuated in the opposite direction across the longitudinal axis 58. The carrier 80 pivots so that the longitudinal axis 116 of the carrier 80 is about 5 to about 50 degrees, about 15 to about 30 degrees, or about 20 to about 25 degrees from the longitudinal axis 114 of the main housing 82 (1). In contrast, when the carrier 80 is not swiveled, its longitudinal axis 116 is generally aligned with the longitudinal axis 114 of the main housing 82 and, therefore, generally with the longitudinal axis 47 of the shaft 42 '. It becomes a straight line.

バネクリップ９４は、使用者の力が無い時、キャリア８０をほんの僅かバイアスでき、いったんキャリア８０が使用者の力に直面するとキャリア８０をより大きくバイアスできる。あるいは、使用者の力が無い時、バネクリップ９４は、バネクリップ９４が使用者の力が在るまでキャリア８０をバイアスしないようにネック２４の側壁９６及び９８の間を自由に動きまわることができ、バネクリップ９４をネック２４の側壁９６及び９８に無理に逆らわせることで、キャリア８０をバイアスする。   The spring clip 94 can bias the carrier 80 only slightly when there is no user force, and can bias the carrier 80 more greatly once the carrier 80 encounters the user force. Alternatively, when there is no user force, the spring clip 94 can move freely between the side walls 96 and 98 of the neck 24 so that the spring clip 94 does not bias the carrier 80 until the user force is present. It is possible to bias the carrier 80 by forcing the spring clip 94 against the side walls 96 and 98 of the neck 24.

図１３及び１４に示されるように、キャリア８０は、着／脱可能な毛プレート１０８又は着／脱可能なフロスプレート１１０を収容してよい。プレート１０８及び１１０は、フック及びループ、スナップ嵌め、摩擦嵌め、ねじ止め（円形のプレート上）等により取り付けられてよい。更に、フロス１１２は、プレート１０８（２）の基盤の上面、キャリア８０（θ３）の上面、又はフロス面１０８（θ４）の長手方向軸線１１８を基準にして約５〜約５０度、約１５〜約３０度又は約２０〜約２５度の傾斜した向きにされてよい。   As shown in FIGS. 13 and 14, the carrier 80 may contain a wear / removable bristle plate 108 or a wear / removable floss plate 110. Plates 108 and 110 may be attached by hooks and loops, snap fits, friction fits, screwing (on a circular plate), or the like. In addition, the floss 112 is about 5 to about 50 degrees, about 15 to about 5 to about the upper surface of the base of the plate 108 (2), the upper surface of the carrier 80 (θ3), or the longitudinal axis 118 of the floss surface 108 (θ4). It may be oriented at an angle of about 30 degrees or about 20 to about 25 degrees.

毛１２０は、毛プレート１１０の上面１２２を基準にして傾斜した向きにされてよい。１以上の毛１２０又は毛の房は、天然又は合成エラストマー材から作られてよい。又、毛プレート１１０は、１以上のエラストマーフィンガー１２４を備えてよい。   The bristles 120 may be oriented at an angle with respect to the top surface 122 of the bristle plate 110. One or more hairs 120 or tufts of hair may be made from natural or synthetic elastomeric materials. The bristle plate 110 may also include one or more elastomeric fingers 124.
